Marine biologist, ocean explorer, and professor David Gruber searches the undersea world for bioluminescent and biofluorescent marine animals. Gruber's discoveries are providing a wealth of new insights into a secret "language" of shining colors and patterns that help many marine creatures communicate, interact, and avoid enemies. He and his collaborators have illuminated and discovered novel fluorescent molecules from marine animals and are searching for connections between glowing sea life and the ability to visualize the inner workings of human cells.
